Your config builds just fine here, using latest -tip:
tip/master 726281b: Merge branch 'tools/kvm'
Kernel: arch/x86/boot/bzImage is ready (#2)
or using x86/apic directly:
tip/x86/apic 1a8880a: x86, apic: Make apic drivers static
System is 3001 kB
Kernel: arch/x86/boot/bzImage is ready (#3)
Has linux-next changed something that triggers this build bug?
